Description

Technical Field

[0001] The technical solution relates to the technical field of the frame of a strapping machine, and particularly refers to a tape guiding frame structure. Background Art

[0002] A strapping machine is an automatic packaging device used for packaging items to be strapped, realizing the packaging work of finished or semi-finished products. The strapping machine includes a workbench and a tape guiding frame arranged on the workbench for guiding the strapping tape.

[0003] For example, in Chinese Patent CN216613401U, this patent discloses a new tape frame device of a strapping machine, including a tape frame support; a plurality of driving wheels arranged in the tape frame support; a plurality of belt assemblies respectively wound around two adjacent driving wheels, and all the belt assemblies surround to form a conveying track for transmitting the strapping tape. The belt assembly includes a plurality of thin belts with the front and rear ends sleeved on the two driving wheels.

[0004] The tape guiding method of the above tape frame device is through the cooperation of a plurality of belt assemblies. The strapping tape is mainly transported on the belt for the tape feeding movement in the tape frame. At present, the assembly of the belt assembly is restricted by the space of the placement groove, and the number of thin belts is large, making the installation of multiple belts in the tape frame troublesome and the installation process more complex, resulting in inconvenient installation and low installation efficiency, which needs to be improved. Summary of the Invention

[0005] In order to improve the problem of low installation efficiency caused by the need to install multiple belts in the tape frame, the technical solution provides a tape guiding frame structure.

[0006] The purpose of the technical solution is achieved as follows:

[0007] A tape guiding frame structure includes an annular frame. The annular frame is provided with a tape guiding channel along the inner side wall. Both ends of the tape guiding channel have a tape inlet for introducing the strapping tape and a tape outlet for discharging the strapping tape. Two driving wheels are arranged in the annular frame. A conveyor belt is arranged in the tape guiding channel and is tensioned between the two driving wheels. The conveyor belt has ventilation holes for adsorbing the strapping tape on the conveyor belt. The width of the conveyor belt is adapted to the channel width of the tape guiding channel.

[0008] Through the above technical solution, when the tape guiding frame structure is in normal use, the driving device drives the driving wheels to rotate. Based on the conveyor belt being tensioned between the two driving wheels, the frictional transmission between the two driving wheels and the conveyor belt realizes the movement cooperation. The strapping tape is introduced into the tape guiding channel from the tape inlet. The conveyor belt drives the strapping tape to surround the tape guiding channel for one week and then discharges it from the tape outlet, so that the strapping tapes are stacked to form a winding effect, thereby completing one bundling. The conveyor belt with ventilation holes adsorbs the strapping tape on its conveying surface, making the strapping tape maintain a stable posture during tape feeding and having better flatness of its attachment to the conveyor belt.

[0009] One end of the conveyor belt is arranged corresponding to the belt inlet, and the other end is arranged corresponding to the belt outlet. The conveyor belt forms a wide belt shape that coincides with the guide belt channel, and its width is adapted to the channel width of the guide belt channel. After the conveyor belt is installed, it can cover most of the conveying paths in the guide belt channel. Preferably, there is one conveyor belt to improve the simplicity of the installation process, reduce the workload of installing the conveyor belt, and make the installation efficiency higher.

[0010] Preferably, the proportion of the width of the conveyor belt in the cross-section of the width of the guide belt channel is greater than or equal to 60%.

[0011] Through the above technical solution, the width of the conveyor belt is limited so that its proportion relative to the guide belt channel is greater than or equal to 60%, making the width of the conveyor belt sufficient to drive the strapping belt.

[0012] Preferably, the annular frame is provided with a blower for adsorbing the strapping belt on the conveyor belt after starting.

[0013] Through the above technical solution, when the blower is started, a negative pressure effect is generated by the operation of the blower, so that the strapping belt can be adsorbed on the corresponding conveyor belt at the beginning of belt feeding, effectively restricting the strapping belt from shifting or wrinkling, and further improving the stability of the guide belt.

[0014] Preferably, a plurality of tensioning components are further arranged in the guide belt channel. Each tensioning component includes an inner tensioning wheel and an outer tensioning wheel, and the rotation axes of the inner tensioning wheel and the outer tensioning wheel are parallel to each other;

[0015] The guide belt channel includes a plurality of sequentially connected channel segments. A plurality of the tensioning components are arranged at the joints between adjacent channel segments one by one. The inner tensioning wheel and the outer tensioning wheel respectively support on the inner side and the outer side of the conveyor belt.

[0016] Through the above technical solution, based on the fact that the guide belt channel corresponds to the annular frame in a ring shape, a plurality of channel segments correspond to different ring edges one by one, and a plurality of tensioning components are arranged at these joints one by one. The inner tensioning wheel supports the inner side of the conveyor belt, and the outer tensioning wheel abuts against the inner side of the conveyor belt, acting on both the inner and outer sides of the conveyor belt at the same time, so that the conveyor belt between adjacent channel segments maintains a tension degree and supports the conveyor belt to make its shape conform to the guide belt channel, thereby improving the guiding stability of the conveyor belt.

[0017] Preferably, a corresponding guide belt frame is arranged beside each tensioning component. A plurality of guide belt frames are arranged corresponding to a plurality of outer tensioning wheels one by one. When the strapping belt moves along the guide belt channel, the guide belt frame is used to guide the strapping belt to jump over the outer tensioning wheel.

[0018] Through the above technical solution, multiple belt guide frames are installed corresponding to multiple external tension wheels one by one. When the packing belt passes through the external tension wheels, the belt guide frames are used to guide the packing belt to jump over the external tension wheels, preventing the packing belt from jamming after contacting the external tension wheels, ensuring the continuity of the packing belt, and thus improving the smoothness of belt guiding.

[0019] Preferably, the belt guide frame has a guiding surface, and the guiding surface can transition at the corner of the conveyor belt.

[0020] Through the above technical solution, the guiding surface contacts and guides the movement of the packing belt surface-to-surface, enabling the packing belt to maintain a continuous and stable movement state when passing through the guiding surface.

[0021] Preferably, the guiding surface is an arc surface.

[0022] Through the above technical solution, the guiding surface is a smooth transition arc surface, which can more precisely control the movement direction of the packing belt, reduce the impact and resistance generated by the corner, facilitate reducing the wear of the packing belt, and further improve the smoothness of belt guiding.

[0023] Preferably, the belt guide frame includes a guide block part and guide strip parts arranged on both sides of the guide block part. The two ends of the guide strip parts are embedded between the conveyor belt and the inner wall of the belt guiding channel, and the guiding surface is formed on the guide block part and the guide strip parts.

[0024] Through the above technical solution, based on the fact that the two ends of the guide strip parts in each belt guide frame are embedded between the conveyor belt and the inner wall of the belt guiding channel, the guide strip parts are connected to the conveying surface of the conveyor belt. When the width of the packing belt is greater than the width of the conveyor belt and less than the width of the belt guide frame, the packing belt can transition from the conveyor belt to the guide strip parts, and then pass through the guide block part and transition to the conveyor belt on the other side of the belt guide frame, further improving the smoothness of belt guiding.

[0025] Preferably, the internal tension wheel is provided with an adjusting component, and the adjusting component is used to adjust the tension of the conveyor belt by adjusting the position of the internal tension wheel.

[0026] Through the above technical solution, one of the internal tension wheels is provided with an adjusting component, which can finely adjust the fixed position of the corresponding internal tension wheel in the belt guiding channel to achieve a suitable tension of the conveyor belt, ensure that the conveyor belt maintains a good operating state after adjustment, and improve the convenience of adjustment.

[0027] Preferably, the adjusting component includes a guide rail seat arranged on the annular frame, an adjusting member sliding on the guide rail seat, and a guide rod connected to the internal tension wheel. The guide rail seat is provided with a guide groove, the guide rod is located in the guide groove, the adjusting member is used to drive the guide rod to move, and the guide rod moves along the guide groove to adjust the position of the external tension wheel.

[0028] Through the above technical solution, one end of the adjusting member passes through the guide groove and abuts against the guide rod. When it is necessary to increase the tension of the conveyor belt, the pushing amount of the adjusting member against the guide rod is increased, driving the guide rod to move along the guide groove, and driving the outer tensioning wheel to change accordingly. The inner tensioning wheel presses the conveyor belt, and the position of the adjusting member is locked after the adjustment to limit its reset. On the contrary, reducing the pushing amount of the adjusting member against the guide rod reduces the tension of the conveyor belt, thereby realizing the function of adjusting the tension of the conveyor belt.

[0029] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0030] 1. In this technical solution, a conveyor belt is provided in the belt guiding channel, and the width of the conveyor belt is adapted to the channel width of the belt guiding channel. The conveyor belt can cover most of the conveying paths in the belt guiding channel, improving the simplicity of the installation process to reduce the workload of installing the conveyor belt and making the installation efficiency higher.

[0031] 2. In this technical solution, a plurality of tensioning assemblies are provided in the belt guiding channel, and each tensioning assembly includes an inner tensioning wheel and an outer tensioning wheel. The inner tensioning wheels and the outer tensioning wheels respectively abut and support on the inner and outer sides of the conveyor belt in one-to-one correspondence, keeping the conveyor belt in tension and conforming to the shape of the belt guiding channel, thereby improving the guiding stability of the conveyor belt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following further elaborates on the specific implementation of the present technical solution in conjunction with the accompanying drawings.

[0039] Embodiment:

[0040] Refer to Figure 1 , a guide belt frame structure, including an annular frame 1. The annular frame 1 is square. The internal space of the annular frame 1 is for placing the object to be packed. The annular frame 1 is provided with a guide belt channel 2 along its inner side wall for the packing belt to pass through. There is a notch at the lower end of the annular frame 1. The through ends of the guide belt channel 2 respectively correspond to a belt inlet 100 and a belt outlet 200 at the notch. Among them, the packing belt is introduced through the belt inlet 100 and exported from the belt outlet 200. Based on the fact that the horizontal height of the belt outlet 200 is higher than that of the belt inlet 100, the packing belt is stacked after going around the guide belt channel 2 once for binding and strapping.

[0041] Refer to Figure 2 and Figure 3 , a conveyor belt 4 is provided in the guide belt channel 2. The conveyor belt 4 is used to convey the packing belt. The conveyor belt 4 forms a ring matching the guide belt channel 2. The conveyor belt 4 is a wide belt. The width dimension of the conveyor belt 4 is smaller than the channel width of the guide belt channel 2. The proportion of the width of the conveyor belt 4 in the cross-section of the width of the guide belt channel 2 is greater than or equal to 60%, preferably between 75% - 90%. In this embodiment, the channel width of the shown guide belt channel 2 is 76 mm, and the specific dimension of the width of the conveyor belt 4 is 63 mm. One end of the conveyor belt 4 is arranged corresponding to the belt inlet 100 and the other end is arranged corresponding to the belt outlet 200.

[0042] There are several ventilation holes 5 on the conveyor belt 4. The several ventilation holes 5 are evenly spaced and arranged along the length direction of the conveyor belt 4. And the length direction of each ventilation hole 5 is inclined with respect to the belt conveying direction of the conveyor belt 4, expanding the proportion of the total ventilation holes 5 in the length of the conveyor belt 4, improving the coherence of adjacent ventilation holes 5, and ensuring a better adsorption effect when the packing belt abuts against the conveyor belt 4. The annular frame 1 is provided with two fans 6 corresponding to the ventilation holes 5. There are two fans 6, both bolted to the lower part of the annular frame 1. When the fans 6 are started, a negative pressure effect is generated near the ventilation holes 5 to adsorb the packing belt on the conveying surface of the conveyor belt 4.

[0043] There are two driving wheels 3 in the annular frame 1. The two driving wheels 3 are respectively located at the belt inlet 100 and the belt outlet 200. The conveyor belt 4 is tensioned between the two driving wheels 3. A driving device is installed through one of the driving wheels 3 to drive the driving wheel 3 to rotate. The two driving wheels 3 and the conveyor belt 4 are friction-driven to achieve movement cooperation, so that the conveyor belt 4 maintains a stable conveying speed.

[0044] The belt guide channel 2 includes multiple channel segments. This embodiment shows a situation where the channel segments have four segments. The four channel segments are connected in sequence to form three connections, and the connections have an angle. A tensioning assembly 7 is also provided in the belt guide channel 2, which includes an inner tensioning wheel 71 and an outer tensioning wheel 72. The rotation axes of the inner tensioning wheel 71 and the outer tensioning wheel 72 are parallel, and at the same time are parallel to the rotation axis of the transmission wheel 3, and both ends are fixed to the relative inner walls of the belt guide channel 2. Three tensioning assemblies 7 are provided, and the three tensioning assemblies 7 are arranged one by one corresponding to the three connections. Multiple inner tensioning wheels 71 are supported on the inner side of the conveyor belt 4, and multiple outer tensioning wheels 72 are against the outer side of the conveyor belt 4, so that the conveyor belt 4 is tensioned on the inner tensioning wheels 71 and the outer tensioning wheels 72, and the shape of the conveyor belt 4 is limited by the cooperation of each tensioning wheel.

[0045] A corresponding belt guide frame 8 is provided next to each tensioning assembly 7. Multiple belt guide frames 8 are arranged one by one corresponding to multiple external tensioning wheels 72. The belt guide frame 8 is located on the side of the corresponding external tensioning wheel 72 away from the internal tensioning wheel 71. When the packing belt follows the conveyor belt 4 for transportation, it is used to guide the packing belt to jump over the external tensioning wheel 72.

[0046] See also Figure 4 Each belt guide frame 8 includes a guide block portion 81 and two guide strip portions 82. The two guide strip portions 82 are arranged one by one on opposite sides of the guide block portion 81. Both ends of the guide strip portions 82 extend outward. When the belt guide frame 8 is installed, both ends of the two guide strip portions 82 are correspondingly embedded between the conveyor belt 4 and the inner wall of the belt guide channel 2, so that the guide strip portions 82 can be connected with the conveyor belt 4. The belt guide frame 8 has a guide surface 9. The guide surface 9 is an arc surface. The guide surface 9 is formed on the guide block portion 81 and the guide strip portion 82, which can make the strapping belt pass more smoothly and is used to further guide the strapping belt.

[0047] One of the inner tensioning wheels 71 is provided with an adjustment assembly 10. The inner tensioning wheel 71 shown in this embodiment is located at the lower end relative to the annular frame 1. There are two adjustment assemblies 10, and the two adjustment assemblies 10 are located one by one on opposite sides of the annular frame 1 along the rotation axis of the inner tensioning wheel 71. Each adjustment assembly 10 includes a guide rail seat 101, an adjustment member 102 and a guide rod 103. The guide rail seat 101 is provided with a guide groove 11, and the groove of the guide groove 11 is arranged in the length direction of the corresponding guide rail seat 101. The guide rail seat 101 is bolted to the annular frame 1. At this time, the guide groove 11 faces the outer wall of the annular frame 1. The guide rod 103 is fixed on the rotation axis of the inner tensioning wheel 71 and embedded in the guide groove 11. One end of the adjustment member 102 is penetrated in the guide groove 11 and abuts against the guide rod 103. The adjustment member 102 adjusts different fixed positions along the length direction of the guide groove 11, and its adjustment direction is perpendicular to the rotation axis of the inner tensioning wheel 71.

[0048] When it is necessary to increase the tension of the conveyor belt 4, the pushing amount of the adjusting member 102 against the guide rod 103 is increased, driving the guide rod 103 to move along the guide groove 11, and driving the outer tension pulley 72 to move accordingly. The inner tension pulley 71 tightens the conveyor belt 4. After the adjustment is completed, the position of the adjusting member 102 is locked to restrict its reset. On the contrary, when the adjusting member 102 moves in the reverse direction to reduce the pushing amount of the adjusting member 102 against the guide rod 103, the pulling force of the conveyor belt 4 acts on the inner tension pulley 71, driving the guide rod 103 to move along the guide groove 11, so that the tension of the conveyor belt 4 is reduced. Thus, the tension of the conveyor belt 4 is adjusted by adjusting the position of the inner tension pulley 71.

[0049] The specific working process of this solution is as follows:

[0050] In this technical solution, a conveyor belt 4 is provided in the belt guiding channel 2. There is one conveyor belt 4. The tensioning assembly 7 shapes the conveyor belt 4 and maintains its tension. The conveyor belt 4 forms a shape that fits the belt guiding channel 2. The conveyor belt 4 has ventilation holes 5, and the ventilation holes 5 are used to adsorb the packing belt on the conveyor belt 4. The conveyor belt 4 is driven by two driving wheels 3 to move the packing belt. The packing belt is introduced into the belt guiding channel 2 through the belt inlet 100 and is exported from the belt outlet 200 along the belt guiding channel 2. The conveyor belt 4 is arranged in a wide belt shape, and the belt width is preferably 41 mm. The width of the conveyor belt 4 is adapted to the channel width of the belt guiding channel 2. The conveyor belt 4 can cover most of the conveying paths in the belt guiding channel 2, improving the simplicity of the installation process to reduce the workload of installing the conveyor belt 4 and making the installation efficiency higher.
